Accelerating Angular Development with Ivy

By: Lars Gyrup Brink Nielsen, Mateus Carniatto, Jacob Andresen

Overview of this book

Angular Ivy is the latest rendering engine and compiler introduced in Angular. Ivy helps frontend developers to make their Angular applications faster, better optimized, and more robust. This easy-to-follow guide will help you get to grips with the new features of Angular Ivy and show you how to migrate your Angular apps from View Engine to Ivy. You'll begin by learning about the most popular features of Angular Ivy with the help of simple stand-alone examples and realize its capabilities by working on a real-world application project. You'll then discover strategies to improve your developer workflow through new debugging APIs, testing APIs, and configurations that support higher code quality and productive development features. Throughout the book, you'll explore essential components of Angular, such as Angular Component Dev Kit (CDK), Ahead-of-time (AOT) compilation, and Angular command line interface (CLI). Finally, you'll gain a clear understanding of these components along with Angular Ivy which will help you update your Angular applications with modern features. By the end of this Angular Ivy book, you will learn about the core features of Angular Ivy, discover how to migrate your Angular View Engine application, and find out how to set up a high-quality Angular Ivy project.

Introducing the Angular Compatibility Compiler

The source code of Angular libraries is compiled before it is published on a package registry such as npm. Until Angular version 12.0, it was not possible to compile Angular libraries using partial Angular Ivy compilation; they had to be compiled with the View Engine compiler. As part of a transition period, Angular uses the Angular Compatibility Compiler to allow Angular Ivy applications to use libraries that are compiled using the View Engine compiler and published to a package registry.

As of Angular version 12.2, the Angular Compatibility Compiler is still included as part of the Angular CLI, meaning that our Angular Ivy applications can consume libraries that are compiled using either the View Engine or the Angular Ivy compiler.

In Angular CLI version 12.0, partial Ivy compilation for Angular libraries was introduced. In short, it compiles all Angular-specific code except component templates. However, partial Ivy compilation...
